It's long talk broken into 7 parts on youtube. I highly suggest everyone watch this when they have an hour to spare.

TLDR: Free energy and UFO's are real. Research "Zero-Point Energy". Quote from Dr. Greer's website "For over 100 years, advances in electromagnetic systems have allowed for the creation of over-unity (more out-put than manmade input) power generation via the zero point energy (ZPE) field and quantum vacuum. Technological progress in the areas of advanced physics and electromagnetic systems, if appropriately supported, will enable humanity to live on the Earth with a minimal footprint with genuine long-term sustainability. For over 100 years, these advanced concepts in energy generation have either been ignored or actively suppressed due to the power of fossil fuel based economic and industrial interests."

The reason we currently are not using free energy is because every time some genius comes up with a great invention for free energy or other disruptive technologies, a corporation would come by and offer that genius millions of dollars to essentially buy ownership of their free energy technology. The genius then says "Well, this corporation just offered me life changing amounts of money so I'm going to sell this technology and be rich for the rest of my life!". Then the corporation takes the technology and puts it on a shelf in a vault, never to be seen again.

OR

Government agents would show up at the inventors house and say "We are going to take all of the stuff you just made and there is absolutely nothing you can do about it."
